1. Create an instance of the state-machine defined in [`app.go`](#core-application-file).
2. Initialize the state-machine with the latest known state, extracted from the `db` stored in the `~/.app/data` folder. At this point, the state-machine is at height `appBlockHeight`.
3. Create and start a new Tendermint instance. Among other things, the node performs a handshake with its peers. It gets the latest `blockHeight` from them and replays blocks to sync to this height if it is greater than the local `appBlockHeight`. If `appBlockHeight` is `0`, the node is starting from genesis and Tendermint sends an `InitChain` message via the ABCI to the `app`, which triggers the [`InitChainer`](#initchainer).

When starting an tendermint instance, the genesis file is the `0` height and the state within the genesis file is committed at block height `1`. When querying the state of the node, querying block height 0 will return an error.
